Abstract

The invention relates to a grinder design and can be used to process pieces of material with an initial size of 10 mm or more. The purpose of the invention is to simplify the design and increase the reliability of the shredder. The crushed material enters the gap between the upper conical disk 4 and the lid 11, where pre-grinding takes place by crushing and cutting between the screw protrusions 12 and the ribs 7. The crushed pieces evenly around the perimeter are hit by fast-moving plates 3 and the fast-moving blades 9. In the working chamber the material undergoes intensive self-grinding, which is facilitated by the fins 10 on the upper disc 4, the corrugations 8 on the disc 2, the plate 3 and beat 9. The crushed material under the action of air flow is directed to the unloading area. 3 il.

The invention relates to devices for measuring p, g: en: and can be used for processing pieces of material with an initial size of 10 mm or more, and for a waste of waste and defective ceramic and metal-ceramic production into fine powder with the upper bound of the size,

The aim of the invention is to simplify the design and increase the reliability of the work.

FIG. 1 shows a shredder, OBPE 3, view 5 in FIG. 2 - airborne A in FIG. L, 5 in —.section BB in FIG. 2 „

The grinder contains split housing 15 two coaxially arranged disks, and the lower disk 2 is mounted for rotation around a vertical axis. and provided with impact plates 3, set at an angle of 35-55 to the diameter of the disk 4 with a slope in the direction opposite to the rotation. The upper disk 4 is made in the shape of a truncated cone with a through central hole 5 that passes into the conical opening 6, in the lower part, while its outer surface has working elements 7 in the form of edges S .1 less. in height to the bottom of the cone. The bottom of the ngoknii disk 2 is provided with radially arranged grooves 8j and in its central part there are beams 9, having convexes and surface in the direction of the disk rotation. On the forming surface of the conical hole 6 there are radio edges 10 The top disk 4 is fixed on the body 1. The cover 11, which is coaxial with the upper disc 4 and which faces the upper disc 4, has a conical surface with a screw protrusion 12 fixed to the lower disc.

The material subjected to grinding enters the gap mezkdu. the upper conical disk 4 and the lid 11, where its pre-grinding by crushing and cutting is performed; bluer 12 and ribs 7. Screw lugs 12 located on the upper disc cover 11, when it rotates, allow the material to move more efficiently into the working chamber. Shredded pieces evenly around the perimeter

under the impact of fast moving impact plates 3 and thrown into the center of the chamber. In this case, pieces of material are hit by a fast moving BIL (they are destroyed upon impact and discarded.) They encounter material thrown by the shock plates 3. on the lower disk 2, the plate 3 and the blade 9. When the lower disk 2 rotates under the influence of centrifugal and inertial forces, the material j lies on the bottom of the disk, it moves upwards and toward the periphery of the crushed material under the action of a stream of air sucked by Without the central hole 5 of the upper disk 4, it is directed to the unloading zone. Particles with a mass equal to the limiting value and pain; they do not have the opportunity to enter the unloading zone. The size limit of the material to be ground is controlled mainly by air flow, the proposed grinder is simpler in design. and reliable in operation -2, since the upper disk is fixed to the housing, and the cover facing the upper disk by a conical surface is fixed on the lower disk. The presence of various comminution mechanisms during operation allows s; If the shredder is compact, its cost price is sufficient, which contributes to the cost of the finished product.
